self consumption and energy flow

I really like metern (now I have it going OK :) ) you have done fantastic work.

I have a query about 2 elements on the detail page self-consumtion and energy flow I get a blank when selected. Are these implemented ?

My system is a single phase and have selected ph0 is this correct?

regards

I am currentlry reworking on meterN, expect a new release soon (mostly core clean-up)

Quite correct I made elect and solar ph=1 and both detail graphs went active so all is good :)

Mine :

Code: Select all

[root@plugbox ~]# find / -name "metern.txt"
/tmp/systemd-private-0ce0d2ebbf6e4dce967b54b528e0e6d8-php-fpm.service-PfKhqX/tmp/metern.txt
[root@plugbox ~]# ls -l /tmp/systemd-private-0ce0d2ebbf6e4dce967b54b528e0e6d8-php-fpm.service-PfKhqX/tmp/metern.txt
-rw-r--r-- 1 http http 30 Jan  9 21:35 /tmp/systemd-private-0ce0d2ebbf6e4dce967b54b528e0e6d8-php-fpm.service-PfKhqX/tmp/metern.txt
[root@plugbox ~]# more /tmp/systemd-private-0ce0d2ebbf6e4dce967b54b528e0e6d8-php-fpm.service-PfKhqX/tmp/metern.txt
1(367.53*W)
2(0*m3)
3(0*l)
As you see, it run as http user in php-fpm (nginx) tmp

Ok Jean Marc,

Many thanks, i am on the right track now !
For the moment i have this output now :

pi@raspberrypi /usr/share/nginx/www/metern/data/csv $ cat /mnt/data_tmpfs/metern
1(21090*Wh)


I will update the other thread with my findings about the script itself...
